Abstract: A találmány eljárás és berendezés kardvívó mérkőzés során lejátszódó· találatok elbírálására. A találmány szerinti eljárás lényege, hogy találatok elbírálásához szükséges megkülönböztetéseket, ill. döntéseket egyrészt a vágásokban, ill. szólásokban rejlő mechanikai impulzus nagyságától, másrészt a két kard közötti, vagy a támadó kard és a találati felület közötti villamos érintkezés, ill. érintkezéssorozat időbeli lefolyásától teszik függővé. Az ugyancsak a találmány tárgyát képező berendezés két találatjelző lámpával ellátott közös áramköri egységből, az utóbbihoz két kábeléren át villamosán csatlakoztatható két kardból, két másik kábeléren át csatlakoztatható és két közös találati felületet alkotó két fémmellényből és két fejvédőből áll, A találmány szerinti berendezés egyik kivitelének lényege, hogy az áramköri egység egy időzítőt tartalmaz, amely a két kard egymáshoz ütközésekor lép működésbe, és a találat jelzést egy előre meghatározott tiltási időtartamra megakadályozza. Továbbá mindkét kard kosarába egy-egy rezgésérzékelő áramkör van beiktatva. A találmány szerinti berendezés egy másik kivitelének lényege, hogy az áramköri egységben egy impulzuskitöltési tényező-mérő áramkör van, amely a találat jelzést csak a támadó kaid és a találati felület közti villamos érintkezéssorozat előre meghatározott kitöltési tényezője esetén engedélyezi Továbbá mindkét kard kosarába egy-egy rezgésérzékelő áramkör van beiktatva. A mindkét kivitelben szereplő rezgésérzékelő legalább három irányban érzékeny kapcsolót alkot, és lehetővé teszi az érvényes találatnak az érintéstől vagy nyomástól való megkülönböztetését.  -1-

Title: Device for the emptying of reservoir
Inventor: HERBERT RECK
IPC: B65F3/04
Filed: 1992-08-07
Abstract: In order to make it possible to empty in particular, large containers with a crew of just one person, an emptying device with a tilting/lifting device 1 and a control unit 4 is described to which a trigger switch 2 is connected which is actuated by the container to be emptied as it approaches the lifting/tilting device and which triggers the raising phase of the lifting/tilting process automatically. When a preset raised level of the lifting/tilting device is reached the control unit interrupts the raising phase. In addition, a first manual actuator 8 to trigger the automatic emptying process, which actuator has an effect upon the control unit 4 only after the interruption of the lifting process, is connected to the control unit. The control unit 4 contains a programmable device 5 into which the preset raised level can be inputted. The programmable device 5 also assumes the function of monitoring the preset time spans, such as the time span between the actuation of the trigger switch 2 and the actuation of the acknowledgement signal switch 3. After the container is emptied, putting the container back down completely is accomplished by means of a second manual actuator 9.

Abstract: 1355360 Alternative pivoting motion windows or doors; stays WILH FRANK GmbH 19 April 1971 [22 April 1970] 27319/71 Headings E1J E2F and E2M A control device for selecting the alternative swivelling or tilting motion about alternative orthogonal axis of the wing or a door or window comprises a stay arm 6 which in use is slidably secured at one end to a guide on the upper part of the wing e.g. casement 2 and at the other end to the fixed frame 1 by means of a swivel bearing 4 for the wing, the arm cooperating for rotation with a first coupling member e.g. fork 11 which is adapted to engage releasably with a second coupling member 9 on the wing and which extends in use into a gap or recess 13 in the rabbet of the fixed frame, the arm 6 and coupling member 11 being arranged in different planes parallel to the plane of the wing. As shown the arm 6 is integral with or detachably secured to a sleeve 14 surrounding the pivot bolt mounted in the swivel bearing brackets 4a, 4b and cooperating with a plate 17 which is pivotally mounted on the vertical bearing axis 7 and to which is secured the fork 11 arranged to receive for swivelling movement of the wing a member 9 slidable on the wing by a push rod 10 located in the rabbet of the fixed frame 1. When the push rod 10 is moved downwardly the member 9 leaves the fork 11 and the wing is free to tilt about a horizontal axis at its lower end. Projection 22 in groove 23 on the plate 17 prevents rotation of the fork about its securing screw 19 when it is loaded by the member 9. Facings 12, 12a fixed on the wing conceal the couplings from view.

Abstract: The invention relates to carrying out a pre-adjustment, before photographing is started, in panoramic X-ray photography using an X-ray device which performs a rotational movement and supports a moving film and an X-ray source. The object is to achieve a correct positioning of the focus in relation to the patient. This is achieved without moving either the patient or the X-ray apparatus, or more precisely, merely by selecting the correct ratio between the film speed and the movement of the X-ray apparatus, instead of mechanical movement. In the apparatus, a viewing member is used, and the correct speed variation curve for the film during the photographing movement is selected on the basis of the position or reading of the viewing member. The film is reeled preferably by means of an electric motor, in which case a sensor can be connected to the sighting member, and the motor is controlled electronically according to the electric output signal of the sensor by means of, for example, a microprocessor.

Abstract: A process and device for selectively separating particles from a suspension is disclosed. The process involves: introducing the suspension into a rotating separation chamber in which the flow is regulated so that the angular velocity of the suspension is maintained slightly higher than the angular velocity of the wall of the chamber. The bulk of the flow of the suspension treated is removed from the separation chamber from a peripheral area. The following fractions are removed separately, simultaneously, and if necessary continuously. The heavy fraction is removed from a zone near of the sidewall; the light fraction is removed from a zone nearer of the longitudinal axis of the chamber, than the heavy fraction outlet and if desired, an intermediate fraction may be removed from at least one separate intermediate zone between the light fraction outlet and the heavy fraction outlet. The apparatus comprises a separation chamber having a longitudinal axis, sidewalls and two ends; inlets through the first end for introducing suspension and auxiliary fluid; rotating means for deviating suspension and auxiliary fluid towards the sidewalls outlets for the heavy and the intermediate fractions in the second end of the separation zone; rotating means to collect the effluents from areas nearer the sidewalls to their respective outlets; and a light fraction outlet is provided in the first end of the separation chamber and is colinearly aligned with the longitudinal axis. Rotating means are provided to rotate the separation chamber around its longitudinal axis. Numerous alternative embodiments are described.
